Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water heater mounting structure suitable for installing a water heater in a pipe shaft (also referred to as a pipe space) of a housing complex, and a bracket for the water heater used therefor.

When installing a water heater in the pipe shaft of an apartment house, the means as shown in FIG. 5 (a) is often adopted (for example, Patent Document 1).
In the figure, a bracket Ba for a water heater is attached to a fixed frame 1 installed in the pipe shaft. The bracket Ba has a frame-shaped portion 4 surrounding the upper, lower, left and right sides of the water heater 3A, and the bracket Ba is attached to the fixed frame 1 by, for example, a receiving piece portion 12 protruding downward from the upper portion of the fixed frame 1. This is achieved by fixing a mounting piece 59 projecting upward from the front portion of the upper plate portion 4a of the portion 4 with a screw body 90 by screwing. The water heater 3A is attached to the bracket Ba using a plurality of screw bodies 91 while being arranged inside the frame-shaped portion 4. The fixed frame 1 is provided with a rotary door 2 capable of covering the front surface of the water heater 3A. The door 2 has an opening for exposing the exhaust pipe 30 of the water heater 3A to the outside. 21 is formed.
According to such a configuration, the upper, lower, left, and right sides of the water heater 3A are surrounded by the frame-shaped portion 4 of the bracket Ba, so that the bracket Ba can be used to reduce the actual space occupied by the bracket Ba. It is possible to stably fix the container 3A. Further, it is possible to make the water heater 3A look good from the front and the like.

  However, in the above-mentioned conventional technique, there is room for improvement as described below.

That is, the water heater 3A may be replaced with a new water heater 3B as shown in FIG. 5B due to a failure or other reasons. Here, the new water heater 3B may not be the same size as the previous water heater 3A but may be larger than the previous water heater 3A. In this case, the dimension L1 from the upper surface of the new water heater 3B to the exhaust tube 30a is often larger than the dimension L2 from the upper surface of the hot water heater 3A to the exhaust tube 30. Therefore, if the bracket Ba having a size corresponding to the water heater 3B is simply used, the height of the exhaust pipe 30a of the water heater 3B (the height of the base portion of the exhaust pipe 30a) becomes equal to the opening of the door 2. Since the position is lower than the position 21, it becomes difficult to expose the exhaust pipe 30a to the outside through the opening 21 as it is.
As a means for solving this, there is a means for using the exhaust adapter 30b bent so as to have a height difference at the front and rear ends. However, if such a means is adopted, it is disadvantageous in terms of cost and the water heater 3B There is also a problem that exhaust resistance increases. Unlike this, it may be possible to replace the door 2, but if such a means is adopted, not only is the cost disadvantageous, but the replacement work of the door 2 is not easy and impractical. .

The above example is an example in which the exhaust pipe of the water heater and the opening of the door are misaligned when the water heater is replaced. It is possible to eliminate it by raising. On the other hand, in the related art, in the frame-shaped portion 4 of the bracket Ba, it is higher than the lower surface of the front portion 40e of the upper plate portion 4a (the upper edge portion of the front opening formed inside the frame-shaped portion 4). The water heater 3B cannot be arranged at the position. When the water heater 3B is attached to the fixed frame 1 or a desired attachment object other than this, there are cases where it is desired to arrange the entire water heater 3B at a position as high as possible. It is not something that can be answered.

The auxiliary piece portion 52 is located closer to the left and right side plate portions 4c than the water heater 3, and is provided so as to avoid interference with the water heater 3 in the widthwise direction of the bracket B. As a result, as will be described later with reference to FIG. 4, when the front cover 33 of the water heater 3 is removed, the front cover 33 can be prevented from interfering with the auxiliary piece portion 52.

  In the structure in which the upper plate portion 4a of the bracket B is screwed to the receiving piece portion 12 of the fixed frame 1 by using the screw body 9b, the receiving piece portion 12 enters the gap 42 formed in the front portion 40, and The standing wall portion 43 is arranged so as to overlap the front surface side of the receiving piece portion 12.

  Next, the operation of the water heater mounting structure A will be described.

  First, as described with reference to FIG. 1, a space 48 existing at a position higher than the lower surface 40a of the front portion 40 is provided below the upper plate portion 4a of the bracket B for the water heater, and The upper portion of the water heater 3 is set to enter the space 48. Therefore, the mounting height of the water heater 3 can be increased. As a result, even if the dimension La from the upper surface of the water heater 3 to the exhaust pipe 30 is relatively large, the exhaust pipe 30 is prevented from having a height lower than that of the opening portion 21, and these heights are matched. By doing so, the exhaust pipe 30 can be appropriately exposed from the opening 21 to the front side of the door 2. It is not necessary to use the exhaust adapter 30b shown in FIG. Therefore, it is advantageous in terms of cost, and it is possible to prevent an increase in the exhaust resistance of the water heater 3 which occurs when the exhaust adapter 30b is used.

  The front portion 40 of the upper plate portion 4a can be detached from other portions of the upper plate portion 4a, as shown in FIG. In this case, the connection of the front portion 40 to the receiving piece portion 12 is also released, but the bracket B is separately screwed to the receiving piece portion 13 of the fixed frame 1 as described with reference to FIG. Therefore, the mounting state of the bracket B to the fixed frame 1 will not be unreasonably released due to the removal of the front portion 40. When the front portion 40 is removed as described above, the front cover 33 of the water heater 3 can be removed on the front side of the bracket B. In the state where the front portion 40 is assembled to the upper plate portion 4a, when the front cover 33 is tried to be removed toward the front side of the bracket B, the front cover 33 interferes with the front portion 40 and the front cover 33 is removed. It is difficult to remove, but by removing the front portion 40, such a thing can be eliminated. When the front cover 33 is removed, the water heater 3 can be maintained from the front side with the main body 32 of the water heater 3 attached to the bracket B, which is convenient. Further, if the front portion 40 is detachable as in the present embodiment, the work of assembling the water heater 3 to the bracket B and the work of removing the entire water heater 3 can be performed more easily and appropriately. Become.

  The present invention is not limited to the contents of the above-described embodiment. The mounting structure of the water heater according to the present invention and the specific configuration of each part of the bracket for the water heater can be variously modified within the scope intended by the present invention.

  The front part of the upper plate part of the bracket for the water heater is preferably removable from the other parts of the upper plate part, but is not limited to this, and the entire upper plate part, for example, a single member is used. It is also possible to make it the structure integrally formed. Note that, instead of or in addition to the means for allowing the front portion of the upper plate portion to be detachable, a means for allowing the lower plate portion of the frame portion of the bracket to be removable from the other portion of the frame portion is adopted. You can also
